抽象工厂模式（Abstract Factory Pattern）是围绕一个超级工厂创建其他工厂。该超级工厂又称为其他工厂的工厂。这种类型的设计模式属于创建型模式，它提供了一种创建对象的最佳方式。
在抽象工厂模式中，接口是负责创建一个相关对象的工厂，不需要显式指定它们的类。每个生成的工厂都能按照工厂模式提供对象。
抽象工厂模式也就是不仅生产鼠标，同时生产键盘。
也就是 PC 厂商是个父类，有生产鼠标，生产键盘两个接口。
戴尔工厂，惠普工厂继承它，可以分别生产戴尔鼠标+戴尔键盘，和惠普鼠标+惠普键盘。
创建工厂时，由戴尔工厂创建。
后续工厂.生产鼠标()则生产戴尔鼠标，工厂.生产键盘()则生产戴尔键盘。
